The vdsBlob table stores the binary data required for performing file-based operations in environments with multiple OneSpan Authentication Server instances, such as DIGIPASS export file (DPX) import or user import via CSV file. Each BLOB is split into chunks, and each chunk constitutes a separate database record.
